Within the body shell 33 is disposed a Figure 6 is an enlarged section taken on the irusto-conical hub engaging socket member 36 'line 6-6 of Figure 3, having an interior taper conforming to the ta- Figure 'l is a fragmentary section taken on .the pered formof the hub sleeve 26 for snug tline l-r-lof Figure 3. Vting engagement thereon. The inner end of the vl socket member 36 is formed integral with an inner shell flange 31. The fia-nge 31 is provided With apertures 38 adapted to receive the studs 35 therethrough when the wheel is assembled.

Against the outer side of the shell flange 31 is mounted an annular fastening ring f5 formed With a pair of diametrically opposed arcuate guide slots 4| engaging headed pins l2 attached to the iiange 31 for attaching the ring to the flange. The guide slots 4| are so formed as to permit a partial revolution of the ring in a clockwise or counter clockwise direction. The ring 40 is also provided, at spaced intervals, with stud engaging slots 43 corresponding in number to the studs of the hub and enlarged at one end to provide an aperture designed to receive the head of each stud 3G therethrough while the reduced portion of the slot is formed to engage the shank portion of the stud and is narrower than the larger diameter of the stud head. In the exterior face of the ring i6 are formed depressions coincident with the slots i3 the depressions being of greatest depth at the enlarged part of the slot, as indicated at 44, and having a bevel or inclination 45 at the reduced part of the slot conforming approximately to the bevel 3| at the underside of each stud head 30. The fastening ring 4i? is furthermore provided with an enlarged arcuate slot 41 having teeth |28 formed at the outer edge constituting a segmental rack.

At one side of the socket member 36 i's formed a shoulder 5 having a radially extending bearing ring 5| formed thereon and provided at the outer end with a pair of spaced parallel ribs 52. In a bore through the intermediate portion of the shoulder 55 is slidably fitted a locking pin 53 reduced at one end to limit the projection of the pin and normally urged to a retracted position by means of a coiled compression spring 54. When the pin 53 is projected inwardly of the socket member it is adapted to engage the groove 21 in the hub sleeve 26.

Within the bearing 5| is rotatably mounted an elongated sleeve 56 extending axially at one side of the socket member 35 and provided, at the intermediate portion, with a notch 51 coinciding with that portion of the sleeve engaging the pin 53 to provide a cam surface. Within the sleeve is rigidly secured a shaft 58 projecting inwardly therefrom and having xed on the inner end portion a spur gear 59 disposed within the slot 41 of the fastening ring and meshing with the teeth of the rack 48. To the outer end of the sleeve 56 is pivotally connected an actuating lever 6|.

The lever 6| is formed with an outward oiTset at the intermediate portion to clear the hub fastening'nut 22, one end thereof being connected with the sleeve 56 by means of a pivot pin 62 while the opposed end is enlarged to form a tubular shank 63. At the outer extremity of the shank 63 is formed an annular flange B4.

Within the shank 63 is slidably fitted a lever fastening pin 65 formed with a shoulder to limit its outward movement and normally urged to a projecting position by means of a coiled compression spring 56 disposed within the shank and acting against the pin. The outer end of the pin 65 is preferably rounded and is disposed to engage an aperture in a U-shaped bracket 51 attached to the wheel body shell. Upon the outer part of the pin 65 is secured a collar 68 disposed at an intermediate position to enable convenient retraction of the pin.

'I'he exterior opening of the body shell 33 is normally, in assembly, closed by means of a detachable hub cap 10.

To replace one of the wheels and the tire mounted thereon, the cap 10 is removed from the wheel and the fastening pin 65 retracted in the tubular end of the lever 6| to disengage the same from the bracket 61. The pin 65 may be ordinarily retracted by hand but if not moved for some time may be difficult to actuate, in which case retraction may be eiected by pliers, as shown at Figure 14. The lever 6| is swung outwardly to disengage the ribs 52 and turned or swung about so as to effect a half turn movement of the sleeve 56 and shaft 58 connected therewith.

As the sleeve and shaft are so actuated the outer end of the pin 53 bearing against the cam surface of the sleeve will be forced outwardly by the spring 54 from the groove 21 in the hub sleeve. Simultaneously with the release of the safety locking pin 53 the rotary operation of the shaft 5S will cause rotation of the gear 59 and partial revolution of the fastening ring 40 in a counterclockwise direction from the fastening position shown at Figure 3 to the releasing position shown at Figure 4. The wheel body may thus be readily dismounted from the axle and hub.

To assemble a replacing wheel body the mechanism is disposed in the releasing position, as shown at Figure 4, and slidably fitted on the hub section, the lever being thereafter rotated and replaced to the locking position shown at Figures 2 and 3.

As will be noted from Figure 11 the under bevel side 3| of each stud 3U is disposed to engage the bevelled surface 45 of the fastening ring when these elements are in co-operative fastening relation. To maintain a proper relation between the ring and the studs for convenient and effective engagement, it is merely necessary t0 retain the axially adjustable hub sleeve 26 in proper position on the hub core, the adjustment being effected to compensate for wear or dislocation of the parts.

It is to be understood that the form of my invention herein shown and described is to be taken as a preferred example of the same, and that various changes as to the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim:-
